The short version

  • Only Buttondown has a free tier, so it costs nothing to try first.
  • Each has a real cost: Buttondown limited built-in monetization compared to Substack, which offers native payment processing; SAP Emarsys core modules including analytics, recommendations and loyalty are licensed separately, so the platform fee in the first quote is rarely the number you eventually sign.
  • They diverge on capability: Buttondown covers Newsletter creation, SAP Emarsys covers Tactics library.
  • Prices and features above were last checked on 31 August 2026.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Buttondown

  • Limited built-in monetization compared to Substack, which offers native payment processing
  • Fewer growth and discovery features compared to Beehiiv or Ghost
  • Smaller community and ecosystem than larger newsletter platforms
  • Basic automation compared to full-featured email marketing platforms
  • No native mobile app for managing newsletters on the go

SAP Emarsys

  • Core modules including analytics, recommendations and loyalty are licensed separately, so the platform fee in the first quote is rarely the number you eventually sign.
  • Licensing counts stored contacts, so a database retained for years costs money every month regardless of whether those contacts are still mailable.
  • Since the SAP acquisition, contracting and support escalation follow SAP processes, which lengthens procurement noticeably for buyers who are not already SAP customers.
  • The product is built around retail patterns, so B2B, media and subscription use cases sit awkwardly on a data model designed for orders and products.
  • Implementation normally involves a partner and runs to a quarter, so the speed advantage of the tactics library only applies after the integration work is finished.
